Powerabout,
When I bought the motor it was in pices and came with two blocks. The original RS block does have the harmonic balancer and I decided not to run that block out of fear of destroying it (the crank). The block you see there is the next larger bore (think it was the 225hp version) and it doesn't have the harmonic balancer. This caused some problems I'm glad I found out early. The harmonic balancer on the RS crank is about 1.1" longer than the standard crank. This didn't allow enough engagement of the driveshaft in the RS lowerunit. I decided to have the gearcase splined and made two stub shafts that will work with either block. Chris Carson did the work, and said that was the hardest drive shaft he had ever worked on.
I'm anxious to get the motor running and to drive the outfit. Headed for the APBA and other Vintage events with it. Went to the APBA driver's school to drive a SST120 to get ready. Great FUN!!! What a ride.
